Dynamic contrast-enhanced MRI (DCE-MRI) was used to calculate maximum synovial enhancement (ME), maximum synovial volume (MV), and the rate of synovial enhancement (RE) in MCP2 and MCP3 of 28 rheumatoid arthritis patients. DCE-MRI variables were associated with EULAR remission, EULAR good or moderate vs no response, and cartilage quality (dGEMRIC) by linear mixed modeling. MRI: magnetic resonance imaging; dGEMRIC: delayed gadolinium enhancement MRI of cartilage; E: estimate; SE: standard error; MCP: metacarpophalangeal joint; EULAR: European League Against Rheumatism.
